Abstract

This short review provides an overview of the recent advances in the direct transformation of propargyl alcohol derivatives to allenes, benefiting from the merger of transition metal and photoredox catalytic systems. Two main strategies are discussed and organized around the mode of activation of the propargyl electrophile C–O bond, i.e., catalytic methods either involving oxidative addition or photoinduced homolytic cleavage as the key elementary steps.
